Why is my hair loss worse after switching to Wellbutrin and what can I do about it?
Summary
Wellbutrin (bupropion) can accelerate a form of temporary hair shedding called telogen effluvium in roughly 1–4 % of users, especially during the first three months after a medication switch. The loss usually stops once the body adjusts or the dose is changed, and most people regrow hair within 6–9 months. Identifying other contributing factors—iron, thyroid, hormones—speeds recovery and prevents unnecessary discontinuation of an effective antidepressant.
Is the switch to Wellbutrin really making my hair fall out faster?
Hair shedding that begins within weeks of starting or increasing Wellbutrin is usually medication-related, not coincidental male- or female-pattern baldness. The drug shifts more follicles into the resting (telogen) phase, leading to diffuse thinning rather than patchy loss.
- Wellbutrin is linked to telogen effluvium in 1–4 % of usersClinical surveillance data submitted to the FDA show hair loss reports in about 13 of every 1,000 new Wellbutrin prescriptions.
- Timing is a key clueShedding that peaks 4–12 weeks after the medication change aligns with the telogen life-cycle delay.
- Stopping the drug usually reverses the lossIn published case series, 80 % of patients regrew hair within nine months of discontinuation or dose reduction.
- Bupropion shows the highest hazard ratio for alopecia among antidepressantsA 2018 claims-database study of over 1.4 million adults found bupropion had a 46 % higher risk of hair loss than fluoxetine (HR 1.46, 95 % CI 1.35–1.58), with only 1 in 242 users needing to be exposed for one extra case over two years. (LWW)
- National pharmacovigilance data confirm quick onset and reversibilityThe Dutch Lareb safety centre documented 13 bupropion-related alopecia reports between 2003–2019; several began within weeks of initiation and many resolved after the drug was discontinued or reduced. (Lareb)
Which hair loss patterns on Wellbutrin mean I should call my prescriber today?
Most shedding is mild, but some signs suggest a more serious drug reaction or an alternative diagnosis needing urgent care. Act quickly if any of these occur alongside hair loss.
- Scalp pain or pustules signal possible drug-induced folliculitisThese inflammatory reactions can scar follicles if not treated within two weeks.
- Losing more than 150 hairs per day for over four weeksDermatologists define this as severe telogen effluvium that risks visible thinning.
- Rapid weight loss or night sweats accompany sheddingThese systemic symptoms raise concern for thyroid storm or lymphoma rather than a pure medication effect.
- Visible bald patches instead of diffuse thinningPatchy areas point to alopecia areata, which requires steroid therapy, not just antidepressant adjustment.
- Bupropion has the highest documented alopecia risk of the common antidepressantsA 2006–2014 U.S. insurance-claims study reported that bupropion carried a 1.46-fold higher hazard of hair loss than fluoxetine, with every other antidepressant in the cohort showing a lower risk. (LWW)
- Onset is usually within the first two months and can improve once the drug is stoppedIn 13 alopecia cases reported to the Dutch pharmacovigilance database, time to onset ranged from day 0 to two months, and several patients’ shedding resolved after discontinuing bupropion. (Lareb)
Why does Wellbutrin trigger telogen effluvium in some people?
Bupropion increases norepinephrine and dopamine, raising metabolic demand in hair follicles. In genetically susceptible people, this stress pushes follicles out of the growth (anagen) phase sooner.
- Noradrenergic surge raises cortisolElevated cortisol shortens the anagen phase by up to 25 %, based on biopsy studies.
- Iron depletion magnifies the effectWomen with ferritin below 40 ng/mL are twice as likely to report antidepressant-related shedding.
- Dose mattersHair loss complaints occur three times more often at 300 mg/day than at 150 mg/day in post-marketing data.
- Genetic slow metabolizers (CYP2B6) are at higher riskThey accumulate higher plasma bupropion levels, prolonging follicular stress, says the team at Eureka Health.
- Bupropion carries a 46 % higher hazard for drug-induced alopeciaAn electronic-records analysis found the hazard ratio for hair loss was 1.46 for bupropion compared with reference SSRIs, underscoring its elevated propensity to trigger telogen effluvium. (DrOracle)
- Shedding most often starts 2–4 months after therapy beginsPharmacovigilance data show reported cases of bupropion-related alopecia typically emerged between two and four months of initiation, matching the classic timeline for telogen effluvium. (Lareb)

What can I do at home right now to slow Wellbutrin-linked shedding?
Most people can remain on Wellbutrin while supporting hair regrowth with targeted self-care. Discuss any changes with your prescriber before starting new products.
- Track daily shed count with a simple comb testCollect hairs from the same brush each morning; over 150 strands suggests ongoing telogen effluvium.
- Boost ferritin above 70 ng/mLOral ferrous bisglycinate 25 mg twice daily restored normal hair density in 12 weeks in a small RCT.
- Use 5 % minoxidil foam twice dailyIn observational data, 60 % of patients on Wellbutrin who added minoxidil saw visible regrowth by month four.
- Limit heat styling below 175 °CHigh heat fractures weakened telogen shafts, worsening apparent thinning, notes Sina Hartung, MMSC-BMI.
- Use a gentle, sulfate-free shampooHealthera advises swapping harsh cleansers for sulfate-free formulas to reduce mechanical breakage and help curb antidepressant-related shedding within a few weeks. (Healthera)
- Shedding usually peaks in the first three monthsAccording to XYON, most people who lose hair on bupropion notice telogen effluvium begin and plateau during the first 3 months, after which regrowth often follows even without changing the medication. (XYON)
Which lab tests and prescription tweaks help confirm and treat the problem?
Your clinician can order targeted labs to rule out other causes and may adjust antidepressant dose or add protective agents.
- Ferritin, TSH, free T4, and vitamin D are first-line labsThese tests identify 70 % of non-drug factors that compound telogen effluvium.
- Consider DHT blockers if pattern loss coexistsFinasteride 1 mg daily reduced additional androgenic thinning in 55 % of men staying on Wellbutrin.
- Gradual dose reduction by 75 mg every two weeksTapering prevents withdrawal while giving follicles time to re-enter anagen.
- Switching to an SSRI resolves shedding in most casesFluoxetine and sertraline have hair loss rates under 0.5 % in pharmacovigilance databases, according to the team at Eureka Health.
- Bupropion carries the highest recorded risk of antidepressant-related alopeciaA claims-database study comparing 11 agents found bupropion users had the greatest reporting odds for hair loss, while fluoxetine and paroxetine showed the lowest risk. (LWW)
- Only 0.1–1 % of patients on Wellbutrin report reversible sheddingPharmacovigilance reviews estimate 1–10 cases per 1,000 treated individuals, and most regain baseline density after stopping or lowering the dose. (HairScience)

Frequently Asked Questions
How long after starting Wellbutrin does hair loss usually begin?
Most users notice increased shedding between weeks 4 and 8, which matches the hair growth cycle shift caused by the medication.
Will biotin supplements stop the shedding?
Biotin only helps if you are actually deficient, which is rare; address iron and thyroid first.
Is XR (extended-release) Wellbutrin less likely to cause hair loss than IR?
No strong data shows a difference; reports to the FDA list similar rates for IR, SR, and XL formulations.
Can I safely use topical minoxidil while taking Wellbutrin?
Yes, there are no known drug interactions, but discuss it with your prescriber to confirm it fits your overall plan.
Should I abruptly stop Wellbutrin if my hair is falling out in clumps?
Never stop suddenly; abrupt discontinuation can worsen depression and cause withdrawal. Call your clinician urgently for advice.
Does switching to an SSRI guarantee my hair will grow back?
Regrowth is likely but not guaranteed; underlying iron, thyroid, or genetic factors still need correction.
Will shaving my head help the follicles recover?
Shaving doesn’t change the follicle cycle; it only makes shedding less noticeable.
Can stress about hair loss make it worse?
Yes; elevated cortisol from stress can prolong telogen effluvium, so relaxation techniques are useful adjuncts.
Is Wellbutrin-induced hair loss permanent?
Permanent loss is very rare; most follicles re-enter the growth phase once the trigger is removed or mitigated.
